What is the end product of light and dark reactions of photosynthesis?

उत्तर
The reaction of photosynthesis can be grouped into two: Light and Dark reactions.
The reaction involving pigments, solar energy, and water that produce ATP and NADPH2 is called a light reaction.
The photosynthetic reactions in which CO2 is reduced to carbohydrates making use of ATP and NADPH2 generated by light reaction are called dark reaction.
The overall reaction of photosynthesis can be written as follows:
\[\ce{CO2 + H2O ->[Solar energy][chlorophyll]C6H12O6 + H2 + O2↑}\]
